What Is a Brake Horsepower (BHP) Check?
A BHP check is a vehicle lookup that reveals a car's Brake Horsepower (BHP) and factory engine specifications using its registration number.
Brake Horsepower checker measures an engine's power output and helps drivers understand performance, compare vehicle variants, and verify whether advertised specifications match manufacturer data.
CarVeto's BHP check tool helps answer "What engine size is my car?" using official manufacturer information, including engine size, BHP, torque, PS (Pferdestärke), and kW (kilowatt).
Motorists use our car BHP check when buying a used car to check Brake Horsepower, confirm the correct vehicle variant, compare engine performance across different trims, and validate advertised specifications.
Our BHP report displays factory performance specifications rather than the vehicle's current power output.
Modified vehicles may require a rolling road (dynamometer) test to measure real-world performance.
Our BHP report helps users compare manufacturer power ratings across different vehicles using consistent BHP, PS, and kW measurements.
What is BHP?
BHP (Brake Horsepower) is the official manufacturer measurement of a vehicle's engine power output before power is lost through the drivetrain.
It indicates a vehicle's engine performance and is commonly used to compare the power of different vehicles.

Frequently Asked Questions (FAQ)
BHP is measured using an engine dynamometer that records engine torque and engine speed (RPM) under controlled test conditions.
The final BHP figure is calculated using the following formula, where torque is measured in pound-feet (lb-ft) and engine speed is measured in revolutions per minute (RPM):
BHP = (Torque × RPM) ÷ 5,252
BHP is measured at the engine before power passes through the gearbox, driveshaft, differential, and other drivetrain components.
This means BHP represents the engine's factory power output before drivetrain losses.
Customers can use CarVeto's BHP check to retrieve the official manufacturer BHP through the vehicle's registration number.
It also provides engine power output, torque, engine size, and other manufacturer performance specifications from DVLA registration records.
BHP in electric cars is measured from the electric motor's torque and rotational speed (RPM) using a motor dynamometer before drivetrain losses, rather than from an internal combustion engine's power delivery.
The motor's power is calculated using the following formula, where torque is measured in pound-feet (lb-ft) and motor speed in revolutions per minute (RPM).
Brake Horsepower (BHP) Formula
BHP = (Torque × RPM) ÷ 5,252
Electric vehicle manufacturers usually provide power ratings in kilowatts (kW), which can be converted into Brake Horsepower (BHP) or metric horsepower (PS) for consistent vehicle performance comparisons.
Comparing the BHP of electric vehicles with petrol or diesel vehicles is not always a direct comparison because electric motors and internal combustion engines deliver power differently.
Electric motors produce instant torque, while petrol and diesel engines develop torque progressively as engine speed (RPM) increases.
Electric vehicle drivetrain design influences how effectively the motor’s power output is transferred to the wheels.
Most electric vehicles use a single-speed reduction gearbox, which minimises drivetrain losses and enables efficient power delivery.
Therefore, an electric vehicle with a lower BHP rating can achieve similar or faster acceleration than a petrol or diesel vehicle with a higher BHP rating.
The difference between HP (Horsepower) and BHP (Brake Horsepower) lies in their scope, measurement method, and power representation.
HP is a general unit used to measure the power produced by an engine or motor, whereas BHP is a specific horsepower rating that measures engine power output before drivetrain losses.
BHP is determined using an engine dynamometer by calculating power from the engine's torque and RPM at the crankshaft or flywheel.
HP of a car may be reported under different industry testing standards, depending on the manufacturer and market.
HP and BHP are often used interchangeably in vehicle specifications, but BHP more precisely describes the engine's measured power output before power passes through the drivetrain.
The difference between torque and BHP lies in the aspect of engine performance they measure.
Torque measures the engine's turning force, while BHP measures the engine's power output by combining torque and engine speed (RPM).
BHP is directly proportional to torque at a given RPM, making both measurements essential for evaluating vehicle performance.
Torque provides strong pulling force for initial acceleration, towing, carrying heavy loads, and low-speed responsiveness.
BHP determines how effectively a vehicle sustains acceleration as RPM increases and influences its maximum top-speed potential.
Torque and BHP complement each other by describing different characteristics of engine performance.
Torque reflects the engine's pulling ability, whereas BHP reflects the engine's overall power output across the RPM range.
The difference between PS and BHP lies in their measurement standard, regional usage, and power values.
PS stands for Pferdestärke, the German term for horsepower, while BHP (Brake Horsepower) measures an engine's power output before drivetrain losses.
PS is commonly used by manufacturers in Germany and many European countries, whereas BHP is widely used in the United Kingdom and other markets that follow the brake horsepower standard.
PS and BHP measure nearly the same engine power, but they are not identical units.
One PS equals approximately 98.6% of one BHP, so a vehicle's BHP figure will be slightly higher than its equivalent PS value.
Manufacturers often publish both PS and BHP to help customers compare vehicle performance across different regional specification standards.
The difference between kW and BHP lies in their measurement system, purpose, regional usage, and power units.
Kilowatt (kW) is the International System of Units (SI) measurement used to express engine and electric motor power, while BHP (Brake Horsepower) is the traditional unit used to express engine power output before drivetrain losses.
kW is the globally standardised power unit, whereas BHP remains widely used in the UK and many automotive markets to describe vehicle performance.
kW and BHP measure the same amount of engine or motor power, but they express it using different units.
One kilowatt (1 kW) is equivalent to approximately 1.341 BHP, making kilowatt (kW) to Brake Horsepower (BHP) power conversion straightforward when comparing vehicle specifications.
